Micro-USB port not working

I have a Nexus 7 (2014) (says ASUS on the back along with the NEXUS name). I've always had a little bit of trouble seating the micro-usb connector for charging but a couple of days ago it indicated that, even though connected, I needed to connect to charger. I moved the cable connector about a little and once or twice it indicated that it was connected and then immediately that it was not. I haven't been able to find that "sweet spot" again and now the battery is dead. I believe that the micro-usb port is loose/bad and am looking for a way to repair or replace the port.

Everything I find on the internet is for 2012 or 2013 models. I would really rather fix this that have to scrap it for something so basic. And, besides, I love the picture clarity and size and the new tablets that are coming out all seem to be larger.

Hi @georgeoomment,

If you are happy to just be able to charge your tablet so that you can use it, it may be easier to purchase a wireless charger, (http://www.amazon.com/gp/product/B0041RR...) than to find a replacement daughterboard (on which the USB connector is mounted) which is compatible with your particular model Nexus 7 2nd gen tablet or to replace the USB port connector itself. You will of course not have USB connectivity, but at least your tablet can be charged and be used.

I'm experiencing the same problem - I didn't realize the 2013 Nexus 7 had wireless charging. Would the wireless charging still work to bring a tablet back if the battery has been depleted?

Hi, I can't say for sure. It may depend on how far the battery has depleted. It may be that you have to let it 'charge' for a few hours before it may even start to charge. I have had this when using USB chargers on depleted batteries. Nothing would happen for about 1-2 hours of 'charging' and then it seems that the battery kicked itself into action and started charging, which then took the normal charging time of about 3 hours. After that it worked normally. I guess what I am trying to say is if you think that it is worth $25 to buy a wireless charger as per the link in the answer (or even better if you can borrow a compatible one initially to see if it will restore the battery) try it and see.

A wireless charger worked for me on a depleted battery in my Nexus 7 (2nd Generation).

My USB charging port was destroyed. The tablet sat for about 18 months, and then I discovered that it could charge wirelessly. I brought a cheap wireless charger and at first it did not do anything. about 2 hours later the front light started to flash and then the charging icon came on. Works perfect. The only thing is I cannot take it out for an extended time unless there is a wireless charging station near.

Looking at the nexus 2nd generation (I assume that is what you mean by 2014 model) tear down guide shown in the link below you can see that the micro USB port is connected to the daughter board located at the bottom of the device. The only way to replace the USB port is to replace this board. There is no point trying to solder on a new port as it would be near impossible and you may also ruin the board unless you are really good at soldering and have the right equipment. You best bet is to try and find a cheap second hand daughter board for it if possible.

This is not a hard problem to fix. The Nexus 7 opens easily and you only need to remove the back to access the USB port. You do not need to disassemble the unit beyond opening. The USB connector is surface mount soldered to the board. The problem is that the physical flexion causes the solder joints to break; in my case, it was a combination of force plus a marginal solder connection on pin 1. You will need a fine tipped soldering iron designed for SMT work. Pins 1 and 5 are connected to a plane, so they need plenty of heat. Reflowing the connections on all the pins did the trick for me. You need not unsolder the connector. I also tightened up the connector itself using some pliers; the housing of the connector is just crimped and it also gets loose. Good luck.

Hi all,

I've been following this thread since about June last year when my Google Nexus 7 2nd gen stopped charging, and I finally took it in to an IT guy last week, telling him in my layman's understanding what everyone had said on here. Anyway he took it apart and yup, the port had come away from the board. It's all been soldered and is now working!

Thanks all :)
